The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, Total Petroleum Systems are defined and Assessment Units are defined and assessed. Each of province is defined geologically, and most province boundaries are defined by major geologic changes. This dataset is a compilation of data that has been studied and published separately, and in some cases adjacent provinces do not share a common boundary. As a consequence, there are numerous gaps and overlaps in this layer.

In 2012, US Geological Survey (USGS) and National Oceanic & Atmospheric Administration (NOAA) embarked on an ambitious project to digitize surficial seafloor data from existing National Ocean Service (NOS) smooth sheets in the Gulf of Alaska including numerous bays bordering the Gulf. USGS and NOAA are using the data for the nation-wide usSEABED project that seeks to compile and unify existing seafloor characterization point data into GIS-friendly data using the dbSEABED program (Jenkins, 1997; Reid and others, 2005; Buczkowski and others, 2006; Reid and others, 2006) and for the North Pacific Research Board’s Gulf of Alaska Integrated Ecosystems Research Program (NPRB, GOA-IERP, http://www.nprb.org/gulf-of-alaska-project)...
From metadata: Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena,...

The data comprise the initial release of landscape disturbance polygons and lines (sites, pipelines and roads) related to natural gas and oil drilling developed prior to the end of 2013 in the 10-county region along the New York - Pennsylvania border. The study area includes the New York Counties of Allegany, Broome, Chemung, Steuben and Tioga, and the Pennsylvania counties of Bradford, McKean, Potter, Susquehanna, and Tioga. The data were collected using high-resolution aerial imagery from the National Agricultural Imagery Program (NAIP) for each available year between 2004 - 2013 within a geographic information system (GIS), along with additional geospatial data on oil and gas drilling permits and locations, administrative...
Reliable estimates of the magnitude and frequency of floods are an important part of the framework for hydraulic-structure design and flood-plain management in Georgia, South Carolina, and North Carolina (study area). Annual peak flows measured at U.S. Geological Survey streamgages were used to compute at-site flood-frequency estimates at those streamgages in the study area based on annual peak-flows records through 2017. Flood-frequency estimates also are needed at ungaged stream locations. A process known as regionalization was used to develop regression equations to estimate the magnitude and frequency of floods at ungaged locations. This model archive provides the inputs and outputs for (1) the at-site flood-frequency...
